I think we should try to introduce some objectiveness. How about Pinside rating (10.000 scale, rounded to 1 decimal place) - IMDB rating (10.0 scale)

PINSIDE - IMDB
AF: 8.6 - 6.9 = 1.7
BSD: 8.1 - 7.5 = 0.6
Congo: 8.1 - 5.1 = 3.0
FlG: 7.8 - 6.5 = 1.3
FS: 7.5 - 4.8 = 2.7
JM: 7.8 - 5.6 = 2.2
LAH: 7.5 - 6.3 = 1.2
T3: 7.5 - 6.3 = 1.2
TS: 8.2 - 6.0 = 2.2
Tron: 8.3 - 6.8 = 1.5

From this standpoint, Congo is the clear winner with Flintstones not too far behind.

And just for fun, movies that are "better" than the pins:

LoTR: 8.7 - 8.8(trilogy avg) = -0.1

--Star Wars Ep IV - VI--
Sega Star Wars Trilogy: 7.2 - 8.6 (avg) = -1.4
DE Star Wars: 7.6 - 8.6 (avg) = -1.0
Stern Star Wars (Pro): 7.5 - 8.6 (avg) = -1.1
Stern Star Wars (Prem/LE): 8.2 - 8.6 (avg) = -0.4
